Axial deep groove ball bearings are manufactured with the normal tolerances (P0) of the radial bearings. P0 is not indicated in the bearing designation.

Bearings can also be manufactured with a greater precision to meet particular requirements.

P6 Restricted tolerance *

P5 Restricted tolerance *

* These tolerance classes are added as suffixes to the bearing designation.

In the standard version (S0) axial deep groove ball bearings are heat treated so that they are generally dimensionally stable up to max + 150 °C. Special heat treatments are required for higher operating temperature requirements.

S1 Operating temperature max. + 200 °C *

S2 Operating temperature max. + 250 °C *

S3 Operating temperature max. + 300 °C *

S4 Operating temperature max. + 350 °C *

* These temperature classes are added as suffixes to the bearing designation.
